The singer posted a page on her Little Monsters social networking site titled ‘Body Revolution 2013’, encouraging fans to embrace and share their perceived flaws.

“My mother and I created the BORN THIS WAY FOUNDATION for one reason: to inspire bravery,” she wrote on the site. “This profile is an extension of that dream. Be brave and celebrate with us your ‘perceived flaws,’ as society tells us. May we make our flaws famous, and thus redefine the heinous.”

She added: “Now that the body revolution has begun, be brave and post a photo of you that celebrates your triumph over insecurities.”

Gaga then posted a picture of herself in her underwear under the caption: “Bulimia and anorexia since I was 15”. On a second picture, the caption reads: “But today I join the BODY REVOLUTION”, with a third adding: “to inspire bravery.” The final picture reads: “and BREED some M$therf*cking COMPASSION.”

Shortly before launching the initiative Gaga addressed recent reports about her supposed weight gain, writing: “My weight/loss/gain since I was child has tormented me. No amount of help has ever healed my pain about it. But YOU have,” she wrote.

“My boyfriend prefers me curvier, when I eat and am healthy and not so worried about my looks, I’m happy. Happier then I’ve ever been. I am not going to go on a psycho-spree because of scrutiny. This is who I am. And I am proud at any size. And I love you, and want you to be proud in any form you may take as well,” she added.
